it's not even a him.. it's an it. they're spam bots, and they can be tedious but as long as the admins keep keeping an eye on it, it shouldn't get out of hand. yes it does get a little tiring always seeing spam, but it can certainly be a lot worse. just be patient, and it'll get taken care of asap. :)
1. SUSPEND SPAMMERS
When you suspend someone from your Ning Network for spamming, our spam team is notified. Your actions strengthen our fight against spam.
2. SET UP A QUIZ
Come up with a question that only potential members of your Ning Network would know the answer to. With thousands of different questions and answers like these across the Ning platform, spamming on Ning becomes a whole lot harder.
3. TURN ON BLOG MODERATION
Many spam attacks can be traced to blog posts. Ning Networks that operate with blog moderation on are much more resistant to spam attacks. Of course, you always have the option of also turning on member moderation, which will stop virtually all spam from reaching your Ning Network, but we encourage you to consider blog moderation first.
4. FOOL THE BOTS
Include a spam-stopping profile question for new sign ups. Like this one: What's 2 + 4? (anti-spam).
5. APPOINT MODERATORS
You don't have to go it alone. If you haven't already created an inner circle of your members to help moderate your Ning Network, consider it.
